ARTHUR H. DILLARD, on LYNOHBURG, VIRGINIA.

\SEAL-LOCK.

SPECIFICATION fcrming part of Letters Patent N 0. 367,375, dated August2, 1887.

A pplication filed March 3, 1887.

To all whom it may concern:

Be it known that I, ARTHUR H. DILLARD, a citizen of the-United States,residing at Lynchburg, in the county of Campbell and Stateof Virginia,have invented certain new and useful Improvements in Seal-Locks; and Ido declare the following toloea full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements inseal-locks; and it has special reference to those designed to be used onfreight cars, and the novel. combinations and the peculiarities of thesaid lock will be more fully hereinafter set forth in the specificationand pointed out in the claim.

In the accompanying drawings, forming a part of this specification, andon which similar letters of reference indicate the same or correspondingfeatures, Figure 1 represents a side elevation of a portion of a car,showing my improved lock thereon with the top plate of the lock removed;and Fig. 2 is a side elevation of the locking-pin.

The letter A designates a freight-car door, and the letter B the frameof the car surrounding it, and to which on one side is attached a hasp,O, pivoted at one end and provided near the other end with a slot, D,through which extends a staple, E, which is securely fastened in thecar-door.

The letter F designates a block of wood or metal, preferably the latter,the same being in the present instance square in form, and havingdrilled through it in a vertical plane a hole, G, which at a pointslightly above the center is provided with laterally-extending slots orkerfs H of a shape similar to the barb of an arrow, and which kerfsextend upwardly and gradually decrease until they become merged in thehole G.

The letter I designates a locking-pin having on either side near the topthereof, downwardly-extending lugs J, made, preferably, of

Serial No. 229,514. (No model.)

spring metal, and adapted to spread and fit themselves into the kerfs H.The lower portion of the pin is cut away, as seen at K, and firmlyfastened at the end or made a part therewith is a tongue, L.

- The operation of fastening a car-door with my improved lock is asfollows: The door being shut, the hasp on the frame is placed, over thestaple, and the pin, after being provided with an inscription-card ofpaper or sheet metal, is then pushed through the staple and up throughthe drilled portion of the plate. When the springlu gs J reach the kerfsH, they expand and fill said kerfs, and their lower ends pressing on thelower surface of the kerfs prevent the pin from coming out.

g It is impossible to withdraw the pin without destroying the cardattached thereto, because it can only be withdrawn from its prescutposition by pressing it still further upward, and this the card resists,as it cannot pass through the staple.

It will be observed that my lock can be easily applied and is durableand simple, and that the cost of manufacture is very low.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In a car seal-lock, the combination,with the car-frame provided with alink pivoted at one end and having a slot near the other, and the doorprovided with a staple which extends through the slot of the link and'aplate above said staple and securely fastened to the door by bolts, thecenter of said plate being vertically drilled or channeled, and havinglaterally-extending kerfs near the upper portion of the drilled portion,of a pin provided at one end with a tag-carrying tongue and near theother with diverging downwardly-extending lugs of spring metal,which fitwithin the kerfs and prevent the dropping of the pin.

In testimony whereof I affix my signature in presence of two witnesses.ARTHUR H. DILLARD. Witnesses:

M. M. ROHRER, R. 0. Jonas.
